六、形容词副词比较级和最高级有规则变化和不规则变化
形容词比较级在句子中的运用：两个事物或人的比较用比较级，比较级后面一般带有单词than。比较级前面可以用more, a little 来修饰表示程度。than后的人称代词用主格（口语中可用宾格）。
形容词、副词的比较级和最高级
一般来说，中文意思是“……的”的词是形容词，而中文意思是“……地”的词是副词。
英语中的形容词和副词，在句子里表示“比较……”、“最……”时，要用特别的形式，即：比较级和最高级。原来的形式称为原级。
注意
形容词最高级前一定要有定冠词the，而副词最高级前则不需要。
形容词、副词的比较级和最高级的构成规则
1．一般情况下，比较级在后面加-er，最高级在后面加-est；
如：small→smaller→smallest
short→shorter→shortest
2．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，最高级加-est；
如：big→bigger→biggest
hot→hotter→hottest
3．以不发音e结尾的单音节词，比较在原级后加-r，最高级在原级后加-st；
如：large→larger→largest
nice→nicer→nicest
4．以“辅音字母＋y”结尾的双音节词，
把y改为i，比较级加-er，最高级加-est；
如：easy→easier→easiest
heavy→heavier→heaviest
5．多数多音节词，比较级在前面加more，最高级在前面加most；
如：beautiful→more beautiful→most beautiful
different→more different→most different
6．有少数形容词、副词的比较级和最高级是不规则的，必须熟记。
如：good→better→best
bad→worse→worst
old→elder→eldest
many/much→more→most
little→less→least
far →furthe-- furthest/
副词的比较级
(1) 形容词与副词的区别 (有be用形，有形用be；有动用副，有副用动)
在句子中形容词一般处于名词之前或be动词之后
⑵ 副词在句子中最常见的是处于实义动词之后, 副词比较级的变化规则基本与形容词比较级相同
